A plurality of pixel formation portions in an image display portion are grouped so that K pixel formation portions form each pixel group, where K is an integer of two or more. The K pixel formation portions forming each of the pixel groups are connected to the same source bus line. Each of the pixel formation portions is provided with a connection control transistor configured to control an electrical connection state between the corresponding source bus line and a pixel electrode. The K connection control transistors included in the K pixel formation portions forming each of the pixel groups become an On state in periods different from one another. A source driver applies a video signal to each of the source bus lines in a time division manner in each horizontal scanning period.
